SWITCH MOUNTING.

Application filed January The present invention relates .to switch mountings.

More particularly the present invention re lates to electric light fixtures and is particularly useful in connection with the type of socket known as a candle socket, though as the description proceeds it will be apparent that the invention is of broader application. The invention will be described with reference to the type of socket known as candle socket in order that conciseness and definiteness of description may be had.

An object of the present invention is to provide a switch mounting which may be readily assembled and which in the case of a lamp socket having a flexible operating member will permit said operating member to assume the position to which it is biased by gravity. A further object is to provide conveniently operated means for controlling the position of an electric light socket in a direction axially of its length.

A further object is to provide lamp socket means which is readily adjustable either axially or circumferentially and which will remain securely in'adjusted position.

A further object is to provide lamp socket means of the candle type which in cases where a pull chain or cord control is used will permit said chain or cord to assume the position which it will tend to assume through the influence of gravity. V

A further object is to provide a socket supporting member readily adjustable for difierent lengths of candle simulating means.

Further objects will appear as the description proceeds. I

Figure Sis a view'of a fixture of a type in common use to which the present invention is particularly applicable.

Referring to Figure 1, the numeral 10 indicates a conduit for the electric wires 1111, which wires are shown broken away but which, as is well known, will be connected to the two terminals of an electric socket, an example of an electric socket being indicated by the numeral 12. Said socket 12 is shown as holding an electric lamp 13. According to the disclosures of Figures 1, 3 and 5, the conduit 10 has mounted thereon the holder 14, which has swedged thereto the collar 15, which collar 15 is provided with the set screw 16, whereby said collar 15 and holder 1 may be held in position on the conduit 10. The holder 14 is adapted to receive and hold the sleeve 17 which houses the socket 12, together with the means for controlling said socket and for supporting said socket. The sleeve 17 may be white or colored, to simulate a candle. According to the embodiment illustrated in Figure 1, a ratchet mechanism is provided for opening and closing the electric circuit through the electric lamp 13, which ratchet mechanism is indicated as a whole by the numeral 18. A pendant operating member 19, preferably flexible, is provided for operating the ratchet 18. As is well known, alternate pulls on the member 19 will open and close the electric circuit of the wires 11-11 through the electric lamp 13. The holder 14 is provided with the aperture 20 to permit the passage therethrough of the operating member 19. It will be obvious, of course that in order to avoid'sticking of the operating member 19, said member should hang naturally, in such a posit-ion as to be clear of the wall of the aperture 20. By reason of the present invention this advantage may be accomplished without any particular skill on the part of the person mounting the electric socket in place.

Projecting downwardly from the socket 12 is the stud 21. Mounted upon the conduit 10 is the collar 22, which may beheld in place by means of a set screw '23. The collar 22 is provided with a pair of upstanding arms 24l-2t adapted to embrace the downwardly extending stud of the socket 12. Encircling the arms 24.2 l is the ring 25. The clownwardly extending stud 21 will be of sufficient size so that when it is lying between the arms 24E24 it will tend to sping said arms outwardly to a small extent to cause the outside Walls of said arms to assume a slight taper. It Will be clear that by pushing up upon the ring 25, when the stud 21 is in place between the arms 24l2l, a gripping action will be had upon said stud, whereby said stud, and consequently said socket 12, will be held securely against either axial movement or rotati ve movement. I V

According to the structure illustrated in Figures 3 screw-threaded and the arms 2 t12 1 have an interiorly screw-threadedportion engaging with the screw-threads on said stud 21. According to this embodiment, also,v when the stud 21 is turned down into screw-threaded engagement with the arms 2 1-2 1 said arms will be sprung apart slightly. whereby the exterior Walls are tapered. When the sleeve 25 is slid upwardly upon said arms 24-24 a very firm engagement is had, preventing .movement of the stud 21.

terior and the arms 24l24 are exteriorly screw-threaded. In this case the sleeve 25 is interiorly screw-threaded. In this case as in the constructions illustrated in Figures 1, 2, 3 and 4, thearms 24-2 1 will be sprung apart slightly when the stud 21 is thrust between said arms, whereby when the sleeve 28 is turned upwardly on the arms 24l24: a firm gripping action is had between said arms and said stud 21.-

According to the embodiment shown in Figure 7, the sleeve 25 is provided with a set screw 26 adapted to engage one of the arms 24 24E. According to the structure shown in Figure '7, the stud 21 may be mounted in proper position between the arms 24, after which the set screw 26 will be screwed in to hold the stud 21 firmly against movement relative to the arms 2424. 7

.It will be understood, of course, that in each of the embodiments of the present invention above described adjustment of the stud 21 and sleeve 25 will be had while the ornamental sleeve 17 1s out ot obstructing relationship therewith, it being a snnple matter to slip the V sleeve 17 into place after the proper adjustment has, been accomplished.

' In practice sleeves of avariety of lengths are used. According to the present invention sleeves of a Wide variety of lengths may be accommodated by a single design of the mechanism embodying the present invention; By reason of the adjustable means for holding the socket 12 the advantage is atand 4, the stud 21 is exteriorlytained, therefore, that the number of parts to be stocked for dinerent lengths of sleeve 17 will be minimized. Notonly is the advantage attained that the elevation of the socket may be readily changed to correspond to the height of the sleeve 1'? being used, but the further advantage is attained that the ratchet mechanism 18 and the operating member 19 may be so disposed that the operating member will fall naturally through the hole 20 provided for said member. This latter feature is important for the reason that the member 19 should lie in avposition in which it may be readily grasped by a person desirto operate same. In the non-adjustable socket holders as heretofore provided it frequently' happens that in order to have the end of the operating member in a position to be conveniently grasped the socket 14 must be mounted on the conduit 10 in such a position that said operating member is twisted intermediate of its length. In structures such as shown in Figure 8, which variety of structure is in common use, the holder portion 14 is fixedly connected to the stem 27, which stem 27 is fixedly mounted relative to a supporting member, such asa wall, 28. The present invention presents decided advantages in connection with the type of bracket shown in Figure 8, inasmuch as the fact that the ratchet mechanism is adjustable rotatively carries with it the advantage that the operating member 19 may fall naturally through the hole 20.

Though certain preferred embodiments of the present invention have been described in detail, it will be clear that many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims. v I r WVhat is claimed is: V

1. In lamp socket mechanism, a conduit for electric wires, elongated holding means mounted on said conduit, an electric socket, a stem carried by said socket said stem having a smooth cylindrical portion adapted to be located between said holding means and having a rotary and axially slidable bearing relationship therewith, and ring means encircling said holding means'ftor holdingsame in gripping relationship with said stem, said holdingmeans being adapted to be freed sulficiently from said stem to permit; longitudinal sliding movement of said stem between'said holding means independently of any rotative movement of said stem. 3 a I it 2. In a candle-socket, a candle cup, a candle sleeve. an electric socket within said sleeve, ratchet mechanism for controlling said said pendant member, and ring means 00- operating with said holding means for holding said stem in adjusted position both rotatably and longitudinally relative to said a holding means, said holding means being adapted to be freed sufliciently from said stem to permit longitudinal sliding adjusting movement of said stem.
